Kon, M.
Abstract
In order to determine the K-scale at Memambetsu, the frequency distributions were calculated, from the data from January to December, 1953. comparing with those at twelve stations. (Sitka, Niemegk, Cheltenham, Toledo, Tucson, Istanbul-Kandilli, San Juan, Teoloyucan, Kakioka, Honolulu, Huancayo, Watheroo). The correlations with K at Kakioka and Kp were studied. As the result of these statistics, the K-scale at Memambetsu was determined as follows.
Lower limits of ranges R for three-hour-range indices K.
K 0 1 2 3 4 5 6 7 8 9
R 0 4 8 16 30 50 85 140 230 350(γ)
